摘　　要：目的 :观察高压注射器不同的上升时间对左心室造影质量的影响。方法 :用随机对照设计比较短上升时间组 (上升时间 =0 .1s)和长上升时间组 (上升时间 =1s)各 5 0例左心室造影的情况。结果 :短上升时间组的室性早搏发生率和平均的室早个数明显高于长上升时间组 ,且造影质量劣于后者。室性早搏个数未发现与性别和年龄相关。结论 :适当地延长高压注射器的上升时间可以减少左心室造影时室性心律失常的发生 ,从而提高图像质量。Objective: To explore the influence of rise time of injection system on the quality of the left ventriculograms. Method: In this randomized study the quality of the left ventriculograms of short rise time group(rise time=0.1s, n=50) and long rise time group (rise time=1s, n=50) were compared. Result: Ventricular arrhythmias were more in short rise time group than in long rise time group and not related with sex and age. The quality of left ventriculograms in long rise time group is better than short rise time group. Conclusion: An appropriate rise time of injection system can decrease the ventricular arrhythmias during left ventriculography and result in a better quality.
